Visual game - "see you don't have to be real"
We will often say "seeing", but knowing that visual is not absolutely relying on the channel of the most intuitive acquisition information. Here I recommend is more famous illusion pictures. Perhaps this illusion comes from the two-dimensional properties of the picture, but for the most basic visual attention is what I advocated here. Three-dimensional and time for space role, I believe it is more worthy of attention.
